IMPROVEMENT IN MACHINES FOR BURNISHING SOLES AND HEELS 0F BOOTS ANDSHOES.

Specification forming part of Letters Patent No. 52,58 1, dated June 30,1874; application filed November 6, 1873.

To all whom it may concern Be it known that we, ORIN WEEMAN and JOHN W.DUNNELLs, of Lynn, in the county of Essex and State of Massachusetts,have invented a certain new and useful Machine for Burnishing Boots andShoes, of which the following is a specification The nature of ourinvention consists in combining, with an adjustable jack of peculiarconstruction, a series of burnishers, which are so shaped and arrangedthat they all act at the same point, and are adapted to do all the workrequired for burnishing all parts of the sole and heel of a boot orshoe.

Figure lis a plan of our invention. Fig. 2 is a side elevation of thesame. Fig. 3 is a vertical section, showing the jacking device indetail.

D is a burnisher made in the form of truncated cone, and placed closelyto the conical burnishers E and E, as shown in Fig. 1. These burnishersare driven by the shafts 0 F, and F respectively, which in turn aredriven by the bevel-gears G U H HK K B being the main or driving shaft,all arranged as shown in Fig. 1.

The above-described device is mounted upon a table, A, which issupported by a standard, A Near the top of this standard we attachaslotted arm, It, Figs. 2 and 3, which serves as a guide for theswinging-jack standard P P This jack-standard P is hung at one end of alever, P, Fig. 2, which is pivoted at P The opposite end of the lever Iis connected to the foot-lever Q by the link Q, so that the operator, bydepressing the link Q, may cause the jack-standard, and through it thejack and shoe, to rise or fall. The form for holding the shoe L isconnected to the bent lever M, Fig. 2,

- by the longitudinal pivot N, so that the form and shoe are free toswing-on their longitudinal axis. This bent lever M is pivoted at M, sothat by moving it up and down the shoe receives a rocking motion on itstransverse axis, and as this bent lever M is also hung on a swingingstandard, M which turns on a vertical shaft, M in the swinging standardP P, it will be seen that the shoe may be turned at will on its verticalaxis. These several motions are communicated to the shoe by means of thehandle N, which, being connected as shown to the bent lever M, it willbe seen that by raising and lowering this handle a rocking motion aboutthe pivot M will be given to the shoe. By moving the handle to the rightor left the'shoe will swing on its vertical axis, and by turning it soas to cause the rod N Figs. 2 and 3, to revolve, motion will becommunicated through the crank-arm N to the slotted arm N and thus givea rocking motion to the shoe about its longitudinal axis N. To move theshoe away from the burnishers it may be pulled directly forward, thusdrawing the entire jack and its standard free from the burnishingdevice; or it may be dropped by taking the foot from the lever Q or bothof these, motions may be made.

The use of the three burnishers D E E depends upon the work to be done.They are, of course, corrugated, and, before operating, slight heat isapplied in any of the known waysas, for instance, by a lighted jet ofgas conducted by a rubber or other tube, and applied to the burnishers.The burnishers may be hollow and each have a minute orifice at the apex,so that, by the draft, heat will more readily operate upon them. In casea shoe is to have side panels only, the lines of the panel-figure aremarked out by a knifecut and then stained, and the two burnishers E andE are chiefly brought into use, and the leather between the panels isleft unsoiled. In case the whole shank is to be burnished, and there areno heels, the shank is prepared by marking and staining, and thenoperating the jack so as to bring the shank under the burnishers, whenall three may be used, covering a large part of the surface to beburnished, and thus expediting the work.

In case the shank and heel, sides and top, are to be burnished, and thefront part or breast of the heel is concave, the surface is firststained and the burnishers are applied to the shank, as beforementioned, and by moving the jack from right to left the burnisher Dwill finish the work close up to the edge of the breast of the heel. Thepoints of the two conical burnishers E E are used to finish the edgesand curves, when a burnisher, as D, could not be brought to bear. Theconvex sides of the conical burnishers are readily applied to theconcavity of the heel, when the heel is concave, and the sides of theheel are pressed against the conical burnishers by raising or depressingthe jack together with the guiding-lever on the jack. Thus, by

means of the foot-lever and themechanisln of the jack, the operator hasfull control of the machine, and canbring the burnishers to bear on anypart of the shank or heel, and any curve or angle on the shank and heeledge of the shoe.

What we claim as our invention, and desire to secure by Letters Patent,is
